Procedure

A suspension of 10.0 g of 5-fluoro-2-methoxyphenol, 52.9 g of ethylenebromide and 14.6 g of potassium carbonate in 50 ml of N,N-dimethylformamide was heated for 11 hours at 80° C. After cooling, the reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with water, dried and evaporated. The residue was chromatographed on silica gel using 50% chloroform-n-hexane as an eluent to give 11.6 g of the desired compound as a colorless oil.
